Abstract :

this paper has scrutinized an effective approach regarding to how to elicit double quasi-sinusoidal waveform with orthogonal angles that can be applicable for two-phase induction motors. Hither, to be more precisely declared that a switching strategy is proposed so that the provided voltages by Matrix Converter (MC) i.e., A and B phases have 90⁰ difference with each other. This switching strategy assists two-phase induction motors aimed at operating in appropriate state. As the created frequency in an important item for this motor, matrix converter can also undertake this function. It is worth mentioning that, the switching is somehow performed until bio-directional switches couldn’t be simultaneously triggered and withal taken place in the accurate switching order. Its related circuit in order to producing appropriate current and voltage has been tested considering MATLAB Simulink and experiment. The simulation result is extracted with respect to inductive and resistive load. Meantime, PWM method is carried out to extract experimental results that clearly show its effectual performance.
